javascript - Split JS string via Regex? -

-

I have MMYY pattern (end of credit card)

me It is necessary to analyze each section (01 and 14): So I tried: 

  '0114'.split (/ \ d {2} / i) // ["", "", ""]   
 It actually sees 2 digits as a separator and therefore I do not get anything.  
 However, I have been able to do this with:  
  '0114' match (/ \ d {2} / ig) // ["01" "14"]   
 But I'm surprised that  split .  
 Can I do  also  with  split ? For example:  
 
 
  "1234" .split (/ (? = $$$) /) = & gt; A common solution for arbitrary length strings seems impossible, the best we can get is something like this:  
   code> str.split (str.plength and 1? / (? = (?:?) *. $) /: / (? = (??? ::)) + $) /)

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
